HAIR DRIER.

Application filed August 6, 1927. Serial No. 211,121.

This invention relates to hair driers and more particularly :to hairdriers of the type illustrated and described in my prior Patent No.1,541,988 of June 16, 1925 and in my 'copending application, Serial No.161,480

filed January 17, 1927.

The objects of the present invention are to provide a generally improvedand simpli-- fied construction that may be economically produced and toimprove the operation of the device.

According to the particular embodiment which I have shown and describedfor the purpose of illustrating the invention and be varied within thescopev of thc appen ed claims, the incandescent lamp or source ofradiant heat and light rays is brought toward the front of the casingand the means for preventing swirling or circular motion of the air andfor directing the same in a straight line through the device is arrangedbehind the lamp and supports the heating element or coil.

The lamp is provided with a reflector, the periphery of which is spacedfrom the interior of the casing and forwardly of the reflector is aninverted conical ring for conccntrating'the air in its passage throughthe The outer diameter of the reflector is preferably substantially thesame as the internal diameter of the opening through the invertedconical ring and the position of the reflector in back of this ringprovides an annular space for the passage of the concentrated airthrough the device.

Rearwardly there is a partition provided with a conical opening adjacentthe rearwardly directed smaller end of which the propeller fordelivering the air through the device is arranged.

The partition defines the opening through which the propeller projectsthe air and this partition may support the blades for preventingswirling of the air, these blades in turn providing an admirablemounting for the electric or incandescent lamp.

A particular embodiment of the invention is illustrated in theaccompanying drawings, in which Fig. 1 is a longitudinal section throughan embodiment of the invention on the line 11 of Fig. 2;

. Fig. 2 is a transverse section taken on the line 2-2 of Fig. 1;

Fig. 3 is a transverse section taken on the scope into the adjacent endof the drum 9 line 33 of Fig. 1 and looking in the oppo site direction;

F ig. 4 is an end view taken from the forward end of the device; and

Fig. 5 is a circui t or wiring diagram.

The device shown comprises an open ended cylindrical shell 5, theforward end oi which forms an open outlet 6. The outlet end 6 may beheaded at 8, for strengthening and finishing the same.

The rear end of the shell 5 is attached'to a cylindrical drum 9 whichforms a continuation of the inner end of the shell 5 and the adjacentends of the shell 5 and drum 9 are secured together through the marginof the partition 30 as will be hereinafter described, the adjacent endof the drum 9 being reflexed at 12, for this purpose.

The drum 9 and Shell 5 may be of suitable sheet metal construction,although this may, of course, be varied widely within the spirit andscope of the present invention.

At the rear end of the drum 9 is an end member flanged marginally at 16to teleand detachably secured therein by suitable screws 18. The endmember 15 may be rolled out adjacent the end of the drum -9 at 19 tofinish the same and provide a shoulder for limiting the insertion of theendmember into the drum 9.

The end member has an axial opening 20 surrounded or defined 'by anintegral hublike portion 21 and an electric motor 22 is mounted in thisopening 20 with the revolvable motor shaft 23 disposed axially withrespect to "the drum 9 and shell 5. For oiling the forward hearing 24for the motor shaft 23, a tube 25 extends radially and is turned at 26out through the end member 15 so'that suitable oil may be intrliduceddtherein and will be conveyed thereby to the bearing for the motor shaft23.

The end member 15 is provided between the hub-21 and its periphery witha plu rality of radially elongated openings 28 which constitute jointlythe inlet through which the air is drawn into the device. This inletmay, of course, be screened if desired.

Arranged forwardly of the motor 22 and mounted in the rear end of theshell 5 is a partition 30 turned longitudinally at 32 to fit snugly inthe shell 5 and flanged radially at 34 to engage in the reflexed end 12of the drum 9, which reflexed end may be firmly pressed upon the flange34 to bind the partition and drum securely together. The rear end of theshell 5 fits telescopically over the annular longitudinally disposedportion 32 of the partition 30 and is detachably' secured thereto as bymeans of suitable screws 35.

The partition 30 has a conical axially disposed opening 36, the smallerend of which opens rearwardly as shown. The fan or propeller 38 isdisposed adjacent the reanoi' the opening 36, preferably with itsforward edge in substantially the plane of the rear end of the opening36. The propeller 38 is suitably fixed upon tie motor shaft 23, as-

by means of a set screw 39 so that it will rotate with the motor shaft,upon rotation of the same, drawing air through the rear inlet openings28 and impelling the same forwardly through the shell 5 and out throughthe outlet 6.

For the purpose of preventing swirling or circular motion of the airthrough the device, the shell 5 is provided, forwardly of the partition30 with a pair of right angle sheet .me'tal anti-swirling members 40 and4:2 with their angular corners adjoining at 44 and their legs extendingradially to substantially the inner periphery of the shell 5 and formingfour blades 46 disposed norrnal or at right angles to each other. Theblades 46 are recessed axially at l8 to receive a socket member 50, thebase 52 of which is secured by screws 53 and suitable cooperating nutsto integral lugs or ears 54 struck transversely from the inner recessededges of the blades d8.

The lamp 58 which may be a high power electric light or incandescentlamp such as a nitrogen or high powered tungsten filament lamp, ismounted in a horizontal position in the socket 50, which may be astandard or ordinary Edison socket. The lamp 58 is positioned toward theforward or front outlet end 6 in the focus of the for wardly directedand preferably polished surface of a reflector 60.

The reflector 60 is positioned forwardly of the blades 46 and has anintegral hub 62 which fits telescopically over the socket 50 at 63. Thehub (32 is split longitudinally, preferably at a. plurality of spacedplaces as indicated at 6 and its rear end is rolled inwardly at (35 toreceive a wire 66 or other suitable means which is wrapped around theinwardly rolled end and clamps the reiiector 6O firmly upon the socket50.

The peri hery of the reflector 60 is spaced rom the inner surface of theshell 5 and Iorwardly or outwardl of the reflector 60 is an invertedCODlCEU, ring 68 with its smalher end opening outwardly at 70. The outeropen end of the ring (38 is spaced outwardly from the periphery of thereflector application, Serial No.

60 at a and the opening 70 which is axially disposed and in substantialalignment with the periphery of the reflector 60 is preferablyofaninternal diameter substantially equal to the external diameter of thereflector 60, although this may be varied. The

rear end of the ring 68 fits snugly at 72 in the shell 5 and may besecured thereto by means of suitable rivets 73, although the mounting ofthis ring may, of course, be detachable if so desired.

A heating coil T5 comprising a suitable metalliewire is woundhelicallyand supported in a substantially closed figure upon the forwardlydirected longitudinally extending portions 76 of the blades 46. For thepurpose of supporting the heating coil on the blades 46 withoutelectrical contact therebetween, the extending portion of each blade hasan opening 78 and'a button 80 of suitable non-inflammable insulatingmaterial is clamped upon one side of each blade 46 adjacent the openings78 by rings 82 having lugs 83 turned in through notches 8% in whichblades 46 are turned back into cooperation with the opposite sides ofthe blades to clamp the insulating buttons 80 firmly thereto.

Three of the buttons 80 are aper'tured at 85 to permit the coil toextend therethrough. One end of the coil 75 is secured to andelectrically connected with a terminal screw 86 on one side oi thefourth button as indicated at the top of Fig. 1 and the opposite end ofthe coil 75 is secured to and electricallyconnected with a terminalscrew 87 on the opposite side of the same button.

The current supply conductor 90 enters the drum 9 through an insulatingbushing 92 as shown in Fig. 3 and its conductors 93 are connected tothree switches 91- 'roupcd together and secured byscrews So to the topof the wall of the drum 9. The group of switches is indicated generallyat 96 and each is provided with an operating handle lever 97, whichextends outwardly and is operable in a slot inthe wall oi the drum 5).

The switches shown are of the toggle lever type more fully disclosed inmy to-pcnding 72,6li' filed December 2, 192".

The lamp 58, motor 22 and heating coil 75 are connected in parallel asshown in 5 with one of the switch levers 9T separately controlling each.The supply conductors 90 are adapted to be connected with any suitablesource or current such as tor example a standard Edison outlet. One ofthe conductors 93 leads to one otlihe contacts of the lampeontrollingswitch and to one oi the contacts of the motor controllingswitch as shown in Fig. 5 and the other conductor 93 leads thrbugh tneheating coil 75 to one of the contacts of the heating coil controllingswitch. The switch levers ,9? operate prel erably with a snap action andby operating one the lamp circuit is opened or closed independently ofthe motor and heating coil opened or closed independently of the'lampand motor circuits.

In carrying out the present invention the lamp 58 constitutes the sourceof radiant heatand radiant light. The rays of light and the heat emittedby the lamp 58 are reflected by the reflector and projected outwardlythrough the outlet end 6 which, in use, is directed toward the hair andscalp or other surface. When the motor circuit is closed, the fan 38'isstarted and air is drawn in through theinlet opening 28 and projectedwith the radiant heat and light through the discharge end 6 of thedevice and upon the hair and scalp or other surface. The cooperation ofthe reflector 60 and conical ring 68 concentrates the air in its passagethrough the device. By closing the circuit through the heating coil 75with the motor and lamp circuits closed, the air may be heated, in addition, as desired in its passage through the device. I

In operation the air is obviously blown across the heater 75 which isarranged between the fan 38 and the lamp 58 and the blades 46 which aredisposed between the fan 38 and lamp 58 and support the heater coil 7 5prevent circular or swirling motion of the air and direct the same insubstantially a straight line through the device.

For supporting thedevice the drum 9 is provided with a pair ofdownwardly depending brackets 100 suitably secured to the bottom of thedrum and pivoted at 102 between these bracket members 100 is the upperheaded end of a post turn suitably secured in a post 104 which fits 103which is in into and is extensibly mounted in an uprig t stand 105having a suitable supporting base 106. For the purpose of securing theextendible post .104 in any desired extended or retracted position, theup right standard 105 is provided with a thumb screw 108.

The rear edges or ends of the blades 46 have integral laterally turnedtongues or ears 110 which fit against and are riveted at 112 orotherwise suitably secured to the partition 30 and thereby firmlysupport the blades 46 upon the partition 30. Those conductors whichextend from the switches 94 on one side of the partition 30 to theheating coil and lamp 58 on the opposite side of the partition 30 may beled through suitable openings 115 in the partition 30.

I do not, of course, intend to be limited to theprecise details shown ordescribed.
